- At Fuyang, deep water method instead of soil drainage was used, the water layer about 10 cm thick was kept for some days near maximum tillering stage, this could result in deterioration of soil environmental condition for rice growth at late stages. 在富阳,用保持深厚水层的办法代替土壤排水,在最大分蘖期保持10厘米厚水层数天,破坏了水稻生长后期土壤环境条件。
- maximum tillering stage 最高分蘖期
- The difference of TU among varieties we net significant in former stage and after heading, hut signiflcant after maximum tillering. 水稻分蘖整齐度品种间差异前期没有达到显著水平,最高分蘖期以后达到显著水平,抽穗后又降低到显著水平以下;
- In 1997,the valid tiller ending phase and maximum tiller phase delayed and leaf ages index increased in medium and late tillering phase under high-temperature. 1997年在分蘖中、后期持续高温,有效分蘖终止期和最高分蘖期向后延迟,叶龄指数增加。
- For late rice, we should pay attention to seedling and tillering stage, supply certain amount at middle stage, if soil K deficiency is severe. 对晚稻施钾来说,我们应注意苗期和分蘖期,如果土壤缺钾严重,中期供应一定数量钾肥。
- It emerged in tillering stage, then increased in earing and then outbreken most heavily in ripen period. 该病在水稻分蘖末开始发病,孕穗末病情剧增,蜡熟进入发病高峰。
- Less nitrogen was accumulated in short-height cultivars than in tall-height cultivars during tillering stage, but the reverse was true after anthesis. 矮秆粳稻4007和武运粳在分蘖期累积的氮素量低于豫粳和云粳,开花期后吸收的氮素显著高于豫粳和云粳。
- Suitable drought at tillering stage could enhance water use efficiency (WUE) of rice plant significantly in the course of and after treatment. 分蘖期适度节水胁迫处理可以显著提高处理期及处理结束到完熟期的水分利用效率;
- The loss of the yield of the r ice irrigated with polluted water at tillering stage is greater than that at ear primordial stage. 生育前期(分蘖期)受污染的产量损失大于生育后期(幼穗分化期)受污染的产量损失。
- Therefore, the management in tillering stage of the grass species wase the key factor for the effective use of the grass. 表明在利用这些草种的过程中应抓好分蘖期的管理工作,以达到充分利用其饲用价值的目的。
- There was significant difference between barley/broad bean intercropping and barley monocropping in barley tillering stage. 大麦/蚕豆间作在大麦分蘖期耗水量比大麦单作高,且存在显著差异。
- To spring wheat,high IAA/(ZR+Z) in tillering stage was benefit to tiller,and to winter wheat,low IAA/(ZR+Z) was benefit to tiller. 春性小麦分蘖初期较高的IAA/(ZR+Z)比值利于小麦分蘖发生;冬性小麦分蘖初期较低的IAA/(ZR+Z)比值利于小麦分蘖的发生.
- The roots was little effect to drought during tillering stage .but it was sensitive between the jointing stage and the flowering stage. 分蘖期干旱对根系生长发育影响较小,拔节后直至抽穗开花期根系对水分胁迫反应最为敏感;
- It suggests that re-watering after water stress in tillering stage has over-compensatory effects on root conformation and absorbing activity. 表明分蘖期胁迫后复水对水稻根系形态和吸收功能均具有超越补偿效应。
- The results indicated that effects of cadmium and copper in soil on physiological properties and spectral reflectance of rice were the most significant at tillering stage. 结果表明,镉和铜拌土生长的水稻在分蘖期受到的影响最明显,无论是在生理上还是在反射光谱方面变化都比较显著。
- The total hours of sunshine duration and the mean temperature during the tillering stage are the most importana meteorological factors for the effective panicle formation. 决定有效穗数的重要气象因子是分蘖期的日照百分率和平均温度。
- In the tiller stage, the nitrogen accumulation quantity of high nitrogen treatment was obviously higher than that of low nitrogen treatment, but it was reverce after the booting stage. 在同一施氮水平和施氮方式下,增施钾肥有利于提高生育后期对氮的吸收。
